Vegetable Broth with Kitchen Scraps – Zero Waste Cooking

Our vegetable stock or vegan broth is made completely from kitchen scraps. When we cook with vegetables, we collect all the peels, tops, and other parts that normally end up in trash, and freeze them. When enough scraps are collected, it’s time to prepare this delilcious vegetable stock.

Besides being a truly zero-waste recipe, this is also a wonderful base for meal prep. You can freeze the broth, and then use it to create soups, sauces, stews and one pot dishes literally in minutes.

Moreover, vegetable peels and tops are often very rich in nutrients, so this vegetable broth recipe is truly healthy and nurturing. When you cook vegetables next time, don’t throw those peels away, make them into a broth and then freeze it instead!
